@strapi/corenpmDescription
Strapi is an open-source headless content management system. In versions from 5.0.0 to before 5.5.2, the lookup operator provided by the document service does not properly sanitize query parameters for private fields. An attacker can access private fields, including admin passwords and reset tokens, by crafting queries with the lookup parameter. This vulnerability is fixed in 5.5.2.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @strapi/core. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update @strapi/core to 5.5.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-56143 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2024-56143 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2024-56143. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
